Abstract (en)
[origin: EP2056279A2] In a plasma display device, a single frame is divided into a plurality of subfields each having a luminance weight value, and a plurality of video signals, each corresponding to the plurality of discharge cells, are converted into a plurality of subfield data indicating whether or not light emission is performed in each of the plurality of subfields. The converted subfield data is changed based on relative light emission rates of the discharge cells so that light emission of the discharge cells is in correspondence.
